How do people prepare for the CMC, Vellore UG entrance exam?

Honestly, there is no specific strategy to prepare for the CMC Vellore UG entrance exam. It’s more than enough if you are preparing properly for the AIPMT. Also, I will suggest you follow just one reference book thoroughly. Arrange as many mocks as you can before the exams and also time yourself. Usually, very basic questions are asked and focus is given to speed rather than complexity. I have many friends living near Vellore who took coaching at a college called Voorhees in Vellore to prepare for CMC. 

In addition to academic preparation, students should also focus on maintaining a healthy lifestyle, including regular exercise and a balanced diet, to ensure they are in good physical and mental health for the exam.

Hope this helps you!
